To all whom it may concern:

Be it known that I, ALMoN ALMY, a citi- Zen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in oil burners.

The object of the present invention is to provide a simple, practical and efficient oil burner of strong, durable and inexpensive construction designed for usein cooking stoves, heating stoves and various other places such as locomotives and the fire boxes of various other furnaces where a burner of this type is desired and equipped with a generating burner adapted to supply the heat for cOnverting into vapor or gaseous form liquid hydrocarbon for a plurality of burners.

A further object of the invention is to generate and supply gas which will burn the same as natural or artificial gas and which will be adapted to be mixed with air prior to entering the burner bodies and which will burn with a blue flame and without fumes.

A further object of the invention is to provide an oil burner equipped with a plurality of generating tubes having wicks adapted to prevent the liquid hydrocarbon from flowing freely through the generating tubes in the form of astream and which will force the liquid hydrocarbon in a thin sheet or body against thejheating surfaces of the generating tubes.

The invention also has for its object to provide an oil burner in which there will be perfect combustion and in which the gen erating tubes will be readily accessible to enable the wicks to be cleaned and maintained free from carbon deposits.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out inthe'claims hereto appended; it bein understood that various changes in the orm, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Like numerals of reference designate corresponding parts in the several figures 01 the drawings.

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, 1 designates a generating burner consisting of a hollow cylindrical body having a perforatedtop 2 and designed to be constructed of cast metalor other suitable material, and having mounted upon it a vertical cylindrical casingv 3, in which is located generating tubes at and 5. The vertical cylindrical casing, which may be constructed of heavy sheet metal or other suitable material, is fitted around the top.

of the generating burner preferably in a recess 7 thereof, and it may be secured to the generating burner or simply fitted around thesame. ,V

The upper end of the cylindrical casing is located beneath thelid receiving opening 8 of the stove 9. While the burner is shown arranged in a. cooking stove 9 of theordinary construction, it may of course be employed in various places where heat of a maximum degree is desired. e

The generatingtu'bes 4t and 5, which are provided with detachable inverted U-shaped sectionslO, are designed to be constructed of cast iron or other suitable material and the said sections 10, which are connected with the inlet and outlet portions 11 and 12 of the generating tubes by suitable couplings or unions 13, are provided with movable wicks 14: preferably constructed of asbestos, mineral wool or other similar absorbent material and adapted to prevent the liquid hydrocarbon from flowing through the generating tubes in a stream and capabio of spreading the liquid hydrocarbon and causing the same to Contact with the heating surfaces of the generating tubes in a thin sheet. This will enable the gas or vapor to be generated from the liquid hydrocarbon with sutlicient rapidity and volume to sup-- ply the burners with the necessary amount of gas. The couplings or unions 1 3 enable the inverted til-shaped section 10 to be readily detached when it is necessary to remove the wick for cleaning or renewing the same and for removing any carbon deposits within the generator tubes. The inlet portions 11. of the generating tubes are connected by pipes 15 with a supply tube or tubular member 16 having a plurality of needle valves 17 corresponding with and controlling the flow of liquid hydrocarbon into the pipes 15. The supply tube or needle valve casing 16 is connected by a supply pipe 18 with a tanl; 1.9, from which hydrocarbon is preferably fed by pneumatic pressure, any ordinary air compressor beinp' adapted to be connected with the tanl; for supplying the compressed air to the same. The stem or member of each needle valve is mounted in av sleeve 20 and it extends through the sup ply tube creasing 16 at one side of the same and cooperates with a valve seat 21 at the opposite side of the same. The valve seat 21 may be formed in the end of the pipe 15 or in any other suitable manner, will be readily understoodf By this arrangement of needle valves, the flow of liquid fuel to any one of the burners may be controlled, and one more of the burners of a stove may be operated.

The generating tubes 1 and are connected with mixing tubes and 23, which are connected respectively with the generating burner 1 and plain or ordinary burners 2st. The mixing tubes are provided with upturned terminal portions and 26, which are preferably threaded into the bottoms of the burn ers 1 and 2st. The outlet portions 12. of the generating tubes, are provided with jet apertures 27 which are arranged to discharge in the mixing tubes, and each of the mixing tubes is provided with laterally extending air inlet arms or extensions 28 of cylindrical form, but any other desired form of arm or extension may of course be employed. The mixing tubes are preferably horizon tally arranged and the jet apertures of the outlet portions of the generating tubes are located. opposite the mixing tubes and the eases";

is discharged, under pressure, from the 'ene ating tubes into the 1111X1I1g tubes and ause the air to flow into the laterally eX 'i iding arms 28 and mix with the gas enering the mixingtubes. The mixture burns with blue flame without fumes and with ierfect combustion, producing a maximum mount of heat from a given quantity of uel. The burners 2% may be of any desired construction, but they are shown in the accompanying drawings as hollow cylindrical formation similar to the burner 1 and pro vided with perforated top walls. The generating tubes 5 may be of any desired numher, and one or more of the burners may of course be employed, and the said mixing tubes are shown in the accompanyin; drawings as located at opposite sides of the generating burner and supported by arms illwhich are located exteriorly of the cylin- I drical casing 3 which is provided with suitable slots 30 to permit it to be readily placed over the generating tubes and removed when required. The jet apertures are preferably formed in caps 31 threaded on to the outlet ends of the generating tubes and extending into the mixing tubes at the inner ends of the laterally projecting arms.

The mixing tube 22 is located below the generating burner and the main or ordinary burners are provided with openings 32 formed in the bottoms of the main or ordinary burners and arranged eccentrically and adapted to permit a rotary movement of the burner 2a to arrange the latter in different positions to accommodate the openings of stoves of different sizes and different arrangement of stove lids. By this adjust mentthe main or ordinary burners may be arranged at different distances from the generating burner.

The )urner is started by a torch 33 pref erably constructed of asbestos or similar absorbent material and provided with a suitable stem 3% and adapted tobe saturated with denatured alcohol or other suitable liquid for supplyingthe heat necessary to generate gas in'the generating tube l that is connected with the generating burner. The torch preferably U-shaped, as shown, to enable it to embrace the'generating tube and when suliicient heat has been developed in the cylindrical casing to operate the generating tubeat, the gas will be generated and the torch will ignite the generating burner after which the" torch may be readily removed and the burner will supply the necessary heat for theg'eneration of gas in all of the tubes and 5.
